I have a 240v, 30a heater for my workshop. I don't want to wire it up permanently, so I put a clothes dryer plug on it, and I un-plug the dryer and plug in my heater whenever I need heat.
This is not the best solution. The plug on the dryer is not made to be repeatedly removed and inserted. It's hard to do, and it would be easy to touch the prongs while they are still in the socket. Do any of you have a suggestion for a different outlet/plug I could consider? One that's made to be plugged and unplugged on a regular basis. The dryer uses four prongs, but the heater only needs three (no 120v components in the heater).
